The eastern shovelnose ray (Aptychotrema rostrata) is a medium-sized coastal batoid endemic to the eastern coast of Australia. It is the most common elasmobranch incidentally caught in the Queensland east coast otter trawl fishery, Australia’s largest penaeid-trawl fishery. Despite this, age and growth studies on this species are lacking. The present study estimated the growth parameters and age-at-maturity for A. rostrata on the basis of sampling conducted in southern Queensland, Australia. This study showed that A. rostrata exhibits slow growth and late maturity, which are common life-history strategies among elasmobranchs. Length-at-age data were analysed within a Bayesian framework and the von Bertalanffy growth function (VBGF) best described these data. The growth parameters were estimated as L₀ = 193 mm TL, k = 0.08 year^–1 and L_∞ = 924 mm TL. Age-at-maturity was found to be 13.3 years and 10.0 years for females and males respectively. The under-sampling of larger, older individuals was overcome by using informative priors, reducing bias in the growth and maturity estimates. As such, the results can be used to derive estimates of natural mortality for this species.

东部铁锹vel （Aptychotrema rostrata）是澳大利亚东部沿海特有的中型沿海蝙蝠。这是在澳大利亚最大的对虾拖网渔业昆士兰州东海岸的水獭拖网渔业中偶然捕获的最常见的弹性支。尽管如此，缺乏对该物种的年龄和生长研究。本研究估计生长参数和年龄在到期日的一个。rostrata是根据在澳大利亚昆士兰州南部进行的抽样进行的。这项研究表明，A。罗斯塔塔表现出缓慢的生长和较晚的成熟，这是弹性分支中常见的生活史策略。在贝叶斯框架内分析了年龄长度数据，冯·贝塔兰菲增长函数（VBGF）最好地描述了这些数据。生长参数估计为大号₀  =193毫米TL，ķ  =0.08年^-1和大号_∞  =924毫米TL。男女的成年年龄分别为13.3岁和10.0岁。通过使用信息丰富的先验方法，可以克服较大的老年人的抽样不足，从而减少了增长和成熟度估计中的偏差。这样，结果可用于得出该物种自然死亡率的估计值。
